Résumé

Chlorothalonil, a fungicide applied for decades worldwide, has recently been banned in the European Union (EU) and Switzerland due to its carcinogenicity and the presence of potentially toxic transformation products (TPs) in groundwater. The spread and concentration range of chlorothalonil TPs in different drinking water resources was examined (73 groundwater and four surface water samples mainly from Switzerland). The chlorothalonil sulfonic acid TPs (R471811, R419492, R417888) occurred more frequently and at higher concentrations (detected in 65-100% of the samples,

Qualité de l'eau

thumb|Eau du robinet La qualité de l'eau est caractérisée du point de vue physico-chimique, biologique et hydromorphologique (dans le cadre de la Directive-cadre sur l'eau, norme européenne). La qualité de l'eau attendue est dépendante de son usage ; les normes à respecter ne seront pas les mêmes selon que l'eau est destinée à être bue, utilisée pour l'irrigation de cultures, ou simplement à alimenter un cours d'eau naturel.

Water treatment

Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use.

Eau potable

thumb|L'eau distribuée au robinet en France doit répondre aux normes de qualité des eaux destinées à la consommation humaine, édictées au niveau européen. Une eau liquide est dite potable (du latin potabilis, qui signifie « qui peut être bu ») lorsqu'elle présente certaines caractéristiques la rendant propre à la consommation humaine. Les standards de référence dans ce domaine diffèrent selon les époques, les pays et, dans certains pays, selon l'autorité responsable de la définition.
